Three possible IA exosomes eluted from beads; (a) antigen-antibody interaction may remain intact, while the antibody-bead linkers are disrupted during elution. Thus, antibodies are attached on the eluted IA exosomes, resulting in expanded sizes; (b) ideally, only the antigen-antibody interaction is affected and eluted IA exosomes will be the same as UC exosomes; (c) tetraspanins (CD9, CD63 and CD 81) are pulled out during the elution, causing IA exosomes' lost volume and partial contents.
